Granted: 1985-08-14
Abstract: 1. Process for the production of ultra- stable zeolites of the Y-type with a cell constant of from 24.20 to 24.60 A and an Al2 O3 content of from 4.1 to 18.4% by weight corresponding to an SiO2 /Al2 O3 ratio of from 6.5 to 39.9, by thermal dealuminisation of activated zeolites of the Y-type by treatment with gaseous halosilane with the exclusion of moisture, subsequent washing with water and drying, characterised in that an Na Y-zeolite which has been activated in a rotary tube and has an Al2 O3 content of from 18.5 to 29.7% by weight, based on the water-free zeolite, corresponding to an SiO2 /Al2 O3 ratio of from 3 to 6.4 and a maximum water content of at most 2% by weight is used as starting zeolite, which starting zeolite is reacted at a temperature of from 150 to 450 degrees C in a rotary tube furnace with the halosilane Si Cl4 which has been diluted with nitrogen as carrier gas in a volume ratio of carrier gas to halosilane of from 0.01 to 1000, the reaction starting at a low temperature in the case of a starting component with a high Al2 O3 content and gradually rising to the desired temperature, the resulting product being tempered in the rotary tube at a temperature of from 200 to 800 degrees C and the resulting product then being washed-out with water until free of the halide and dried.

Title: Procedure for manufacturing paper bags
Inventor: RANTANEN KEIJO
IPC: B31B37/00
Filed: 1982-04-01
Granted: 1987-01-15
Abstract: The invention concerns a procedure for manufacturing paper bags. The paper bags (10) have been provided at both ends with a sewn seam (15) and the paper bag (10) has in its corner a valve aperture fitted with a collar. With a view to avoiding the cutting of separate collar blanks which has to be done manually, and their fitting, the valve aperture and the repeated running of the paper bag blanks through the production line, the procedure of the invention teaches to affix collar blanks to a full width paper web with a given spacing. Hereafter, the full width paper web is run to assume tubular form and cut in fixed lengths whereby the paper bag in tubular form comprises a shell with both ends open and carrying in its corner a collar blank. Finally on the paper bags in tubular form is performed folding of the corner and sewing of both open ends, whereby a finished paper bag (10) is obtained. It is advantageous for collar blank to use a collar blank, furnished with an incision, a collar blank from which a substantially segment-shaped piece has been removed or a collar blank from which a substantially triangular piece has been removed. On the edge of the collar blanks preferably an oblique cut has been made.

Abstract: Radiation sensitive compositions are image-wise exposed and developed to form an image which is then heated to improve its strength as a lithographic printing image or etch resist. The heating is carried out in the presence of a heat sensitive dye which undergoes a colour change at a temperature of at least 180°C so as to obtain an indication of whether or not the heating has been adequate. The dye may be an integral component of the composition or it may be applied to the image, after development, in combination with a substance capable of forming a shield against contaminating residues produced during the heating step.
